Title: Improvements in hydraulic slide valves
Inventor: NICHOLL EDWARD JAMES
IPC: F16K31/42
Filed: 1950-12-19
Abstract: 694,059. Fluid-pressure servomotor-control systems. DOWTY EQUIPMENT Ltd. Dec. 10, 1951 [Dec. 19, 1950], No. 30929/50. Class 135 A hydraulic slide valve for reversibly connecting each of a pair of service conduits 10, 11 to.pressure and return conduits 7, 8 respectively, comprises a slide member 17 held on its seating face 13 by a spring-loaded thimble 15 and engageable at its ends by annular members 23, 24 and pistons 25, 26 slidable in the members 23, 24 respectively. Looseball pilot valves 47, 61 operable independently by solenoids 35, 36 control the annular members and the pistons. When both solenoids are de-energized the ball valves 47, 61 are urged on to their upper seats by pressure liquid from the conduit 7 which passes through passages 38, 43 and 57, 58 to the rear of the members 23, 24 and pistons 25, 26 whence the slide 17 is held in its neutral position, by the members 23, 24 which abut stops 31, 32 spaced apart a distance equal to the length of the slide 17. To connect, e.g. the service conduit 10 with the pressure conduit 7 and the service conduit 11 with the return conduit 8. the solenoid 35 is energized whence the ball 47 is moved to its lower seat and pressure liquid behind the member 23 and piston 25 is released to the return conduit 8 through passages 43, 19. The pressure still acting on the piston 26 moves the slide 17 to the right which in turn moves the member 23 and piston 25. To return the slide to its neutral position the solenoid 35 is de-energized, the member 23 and piston 25 again being subjected to pressure whence the pressure acting on the piston 25 balances that acting on the piston 26, the slide 17 being moved to the left by the member 23 since the member 24 is in abutment with the stop 32.

Title: Improvements in and relating to the springing of vehicles
IPC: B60G11/08
Filed: 1933-11-08
Abstract: 412,478. Spring-suspensions for vehicles. DAIMLER-BENZ AKT.-GES., Untert³rkheim, Stuttgart, Germany. Nov. 8, 1933, Nos. 31059 and 31060. Convention dates, Aug. 23 and Aug. 31. [Class 108 (ii).] In a spring suspension for vehicles with independently displaceable wheels, the movements of the wheels are guided and corresponding wheels on opposite sides of the vehicle are connected by means of leaf springs, leaf springs and links, or similar mechanism, adapted to pivot about a substantially vertical axis on the frame, such pivotal movement being restrained by elastic means such as rubber cushions. In the arrangement shown in Figs. 1 and 2, the wheels are mounted at the ends of a transverse spring b which pivots with respect to the frame member a, a1 about the axis of a pin c, while a spring clip z rigidly connected to the spring has an arm e projecting between rubber buffers d disposed in the fork a1 of the frame, whereby swinging movement of the spring b from its central position can occur only against the action of the buffers. Modifications are described in which the single spring b is replaced by upper and lower leaf springs, or by a lower leaf spring and a pair of upper levers, each of which near its mid-point is pivoted to a side member of the chassis and at its inner end bears upon a helical spring. In a construction of the character last referred to the single clip z may, as shown in Figs. 6 and 7, be replaced by a two-part clip c<1>, d1, from the upper part cl of which extends a pair of arms m<1>1, m<1>2, adapted through sleeves n<1>1, n<1>2 and bushes q<1>1, q<1>2 to bear against rubber buffers p<1>1, p<1>2 abutting against an extension o<1> of the frame member or bearing g<1>. By providing a ball joint between the upper end of the steering swivel and the corresponding lever, only the transverse spring need be mounted on the vertical pivot, since the ball joints will accommodate the swinging movements of the spring.

Title: Apparatus For Piling Elongated Workpieces Such As Slabs, Billets Or Bars
Inventor: GREENBERGER JOSEPH IRWIN
IPC: B21B39/00
Filed: 1966-07-11
Abstract: 1,150,895. Rolling. UNITED ENG. & FOUNDRY CO. 11 July, 1966 [12 July, 1965], No. 31100/66. Heading B3M. [Also in Division B8] A device for stacking elongated workpieces such as billets from a rolling mill includes means to assemble a group of workpieces on a support movable between two elevations, the support engaging the workpieces on at least two sides during such movement and, at one elevation, forming a continuation of the transfer table to which workpieces are transferred from a roller table. The workpieces are fed in endwise on rollers 11 to abut a stop (46), Fig. 1 (not shown), or an intermediate stop 47, according to whether one or two stacks are to be formed. In the latter instance, two workpieces are arrested to lie end for end and are swept on to arms 23 of the support by pusher elements 16. Alternatively, a single full length workpiece is swept on to the arms. When a row of desired length has been assembled, the arms swing down through preferably somewhat less than 90 degrees and further pusher elements 35 remove the row to form, with preceding rows, a stack on skids 32. Arms (54) in a modification, Fig. 4 (not shown), may overlie the row on the arms 23 during movement, to prevent undesirable displacement. A removable support 55 may receive single layers of articles when stacking is not required.

Title: Improvements relating to brake mechanisms
IPC: F16D51/48
Filed: 1950-12-21
Abstract: 699,304. Internal shoe-drum brakes. DAIM LER-BENZ AKT.-GES. Dec. 21, 1950 [Dec. 21, 1949; Dec. 21, 1949], No. 31106/50. Class 103 (i). A self-energizing brake comprising floating shoes acted upon by restoring springs has that end of a primary shoe which transmits servo force to a secondary shoe lifted away from the drum by a spring which is separate from the restoring springs and has its lifting action limited by an adjustable anchorage, and has, for manual operation of the brake, a thrust member pivoted at one end to the primary shoe and at its other end to a lever engaging the secondary shoe, the line joining said pivots extending substantially parallel to the direction of the forces of the restoring springs. In the brake for a motor vehicle shown, the ends of the shoes 3, 4 are slidably engaged by the forked ends 6, 9 of the pistons 11, 11a of an hydraulic actuating cylinder 13 and by the forked ends 7, 8 of screws 15, 19 carried by adjusting sleeves 17, 20 which are slidably and rotatably mounted in a cylinder 18 fixed on a back plate 12. Springs 21, 22, 25 normally hold the shoes clear of the drum 5. The end 3a of the shoe 3 is held clear of the drum by a spring 33 which is wound with initial tension and is eccentrically mounted on a pin 34 in the back plate. Upward movement of the shoe is limited by closing of the coils of the spring. Alternatively a stop may be adjustably mounted on the back plate 12. For forward movement of the vehicle, corresponding to a rotation of the drum 5 in the direction of the arrow 14, the shoe 3 acts as a primary shoe and transmits servo force to the secondary shoe 4 which moves the piston 11a until a shoulder 11b thereon abuts the cylinder 13. During braking in the reverse direction the shoe 4 is allowed to become the primary shoe by virtue of the yielding of an undulating spring washer 36 disposed between a shoulder 23 on the screw 20 and the cylinder 18. The strength of the spring 36 is such that it is not compressed by the spring 22. The brake may be applied manually by a lever 26 pivoted at 28 to the shoe 4 and at 29 to a thrust rod 30 pivoted at 31 to the shoe 3,

Abstract: 671,304. Damping undercarriage shimmy oscillations. HOUDAILLE-HERSHEY CORPORATION. Dec. 5, 1949 [June 4, 1949], No. 31150/49. Class 4. [Also in Groups XXXII and XXXIV] Shimmy oscillations of an aircraft undercarriage strut are reduced by a liquid damper comprising two sets of interleaved rotary discs immersed in a viscous liquid, for example a silicone liquid of 30,000 centistokes viscosity, one set of the discs being carried by a hub member 19 keyed to the lower end of the fixed portion 13 of the strut and the other set by a member 31 connected to the movable portion 12 of the strut by torque links 51, 52. The member 31 is screwed into a cover 32 to form an annular chamber for the damping liquid, sealing rings 34, 45 being provided at the rubbing surfaces on the hub member 19. As shown in Fig. 3 each set of discs is provided with annular spacers retained in position by bolts 29, 39 respectively, but if desired the spacers for one set of discs may be omitted, so that the latter are in floating engagement with their retaining bolt, Fig. 4 (not shown). The clearance between the surfaces of adjacent discs is very small, such that viscous shear forces rather than frictional drag forces are brought into play to resist rapid shimmy oscillations, relatively slow movements of the rotary members however taking place freely with little resistance.

Abstract: 359,203. Fluid pressure brakes; shoes acting on drums. HALL, F. H., Cleeve Cottage, Holford, near Bridgwater, Somerset. Oct. 20, 1930, No. 31364. [Class 103 (i).] Brake shoes 3 are applied to the drum 2 by a downwardly moving fluid-pressure operated piston 12 disposed within the brake-drum and acting on toggle-links 17,18 connected to the shoes. The shoes may also be applied mechanically by a hand-lever connected to a lever 26 carrying a cam 25 engaging the link 18. The piston rod 14 has a coned end 16 engaging the boss of the link 18. The initial angle of the links 17, 18 may be adjusted to obtain varying leverages by providing a series of pivot holes 27 in the brake shoes for the connection of the links. The cylinder 1 is a casting provided with a plate 4 for attachment to the fixed anchor plate 6 of the brake and has a rearward extension 7 formed with a supply pipe connection 8 connected by passage 9 to the upper end of the cylinder. A bleed passage 10 for letting out air in the case of a hydraulic brake is closed by a plug 11. To prevent oil that may leak past the piston from getting upon the brake shoes, the inner surface of the closure plate 15 of the cylinder is slightly conical and a passage 24 leads from above it to the exterior of the brake drum.

Title: Improvements in or relating to electric switches

Filed: 1926-12-13
Abstract: 285,605. General Electric Co., Ltd., and Angold, A. E. Dec. 13, 1926. Automatic circuit-breakers. - High - speed circuit-breakers of the type described in Specification 254,455 are retained in the closed position by a permanent magnet, a load winding being associated with the hold-on magnet in a manner similar to that described in Specification 252,514, the release of the circuit-breaker occurring in dependence of on a magnetizing force which tends to increase the flux density in the permanent magnet, so preventing any weakening of this magnet. As shown in Fig. 1 the movable contact-carrying arm 4 is held in the closed position by an armature 13 engaging polar projections 26, 27 of a permanent, magnet 16, the armature being carried at the end of a lever 22 pivoted at 24 which is itself connected by a link 23 to the arm 4, the members 22, 23 forming a toggle. The permanent magnet 16 is associated, as shown in Fig. 2, with a winding 30, 31 carrying the load current, this winding being placed upon outer extensions 28, 29 of the pole peices 26, 27. As the current in the winding 30, 31 increases, owing to the fact that its M.M.F. opposes that due to the permanent magnet in the pole-pieces 26, 27 and the armature 13, the flux of the permanent magnet is directed from this path into a path including the polar extensions 28, 29 and the air path between them and at the same time an additional flux in this path is set up by the load winding. Thus a point is reached when the attraction of the armature 13 is no longer sufficient to overcome the action of the spring 11, the flux through the permanent magnet being however increased during the circuit breaker release. As the magnetic circuit of the load winding 30, 31 possesses great reluctance by including a large air gap, this winding may be of large ampere-turns and suitable portions of the magnetic circuits may be laminated in order to obtain quick response with suddenly changing currents. The polar extension 28, 29 may carry a separate opening winding which may be controlled by a reverse-current relay. The degree of overload caused by operation of the circuitbreaker may be varied by adjust ably mounting the armature 13 with respect to the link 22 or by varying the position of the hold-on magnet 16 and its associated parts about the centre 24.
